Shellback (born as Karl Johan Schuster), is a Swedish songwriter, record producer and musician. Shellback was listed as the No. 1 producer of 2012 on Billboard Magazine's year end chart, and he also topped the list of their "Top 10 Songwriters Airplay Chart" the same year. He regularly collaborates with songwriter Max Martin, and together they've written songs for P!nk ("So What", "Raise Your Glass", "Fuckin' Perfect"), Taylor Swift ("We Are Never Ever Getting Back Together", "I Knew You Were Trouble", "22"), Adam Lambert ("Whataya Want from Me", "If I Had You"), Britney Spears ("If U Seek Amy", "3", "I Wanna Go"), Usher, ("DJ Got Us Fallin' in Love", "Scream"), Maroon 5 ("One More Night"), and Christina Aguilera ("Your Body"). Shellback has collaborated with fellow producer Benny Blanco for "Payphone" and "Moves Like Jagger" by Maroon 5 and "She Doesn't Mind" by Sean Paul, and has even gone on his own producing "Want U Back" by Cher Lloyd. A lot of songs that Shellback has co-written have charted within the top 10 on the Billboard Hot 100 in the United States, while others have been at No. 1 on the World Chart.
Born and raised in Karlshamn, Sweden, Schuster started out as a drummer in local indierock bands in Karlshamn, before joining the hardcore/metal scene as a vocalist. At the age of 16, Schuster met Max Martin through their mutual friend Julius. By that time, according to a recent interview in the Swedish music magazine "Stim-magasinet", Schuster said his taste in music was "too cool for school" and he had no interest in pop music whatsoever. Julius kept sending Schuster's indierock/deathmetal demos to Max, who became curious about what it would sound like if Schuster would make pop music. So in 2006 Max invited Schuster to his studio in Stockholm to record a demo with him, and since 2007 Schuster has been signed to Max's production company Maratone.
